What is the arcuate ligament complex?
What is the arcuate ligament complex?
The posterolateral ligamentous complex (also known as the arcuate ligamentous complex) of the knee is an important stabilizer and consists of a number of structures. Depending on the publication/definition more or less of the following structures are included 1-4: lateral (fibular) collateral ligament. arcuate ligament.
What is the function of the arcuate ligament?
The arcuate ligament is one of many structures providing posterolateral stability of the knee. Any injury or trauma to the lateral side of the knee is likely to injure the posterolateral knee structures.
What is the arcuate popliteal ligament?
: a triangular ligamentous band in the posterior part of the knee that passes medially downward from the lateral condyle of the femur to the area between the condyles of the tibia and to the head of the fibula — compare oblique popliteal ligament.
What passes through medial arcuate ligament?
The median arcuate ligament is formed by the right and left crura of the diaphragm. The crura connect to form an arch, behind which is theaortic hiatus, through which pass the aorta, the azygos vein, and the thoracic duct.
Is MALS serious?
A group of nerves in the region, called the celiac plexus may also be affected. MALS usually results in severe and chronic abdominal pain. It is interesting that not all individuals with compression and even severely impaired blood flow of the celiac artery have symptoms.
What passes through the median arcuate ligament?
The median arcuate ligament is a band of tissue shaped like an arc in the lower part of your chest. It passes over the aorta — a blood vessel that carries blood from the heart. When you have MALS, this ligament sits lower than usual and presses on the celiac artery.
Are menisci ligaments?
Menisci rests between the thigh bone femur and the tibia and there are two knee joint ligaments. They are a type of cartilage in the joint. The rubbery texture of the menisci is due to their fibrocartilagenous structure. Their shape is maintained by the collagens within them.
What are the arcuate ligaments of the diaphragm?
The lateral arcuate ligament (also lateral lumbocostal arch and external arcuate ligament) is a ligament under the diaphragm that arches across the upper part of the quadratus lumborum muscle. It is traversed by the subcostal nerve, artery and vein….

What kind of injury is the arcuate ligament?
Arcuate Ligament: Injury. The arcuate sign is an avulsion fracture of the proximal fibula at the site of insertion of the arcuate ligament complex and is usually associated with cruciate ligament injury. The avulsion fracture is usually small, less than one centimeter, and involves the styloid process of the fibula.
What kind of fracture is the arcuate sign?
The arcuate sign is an avulsion fracture of the proximal fibula at the site of insertion of the arcuate ligament complex and is usually associated with cruciate ligament injury. The avulsion fracture is usually small, less than one centimeter, and involves the styloid process of the fibula.
Which is branch of arcuate ligament contributes to posterior capsule?
Lateral branch of arcuate ligament contributes to posterior capsule. Popliteofibular ligament is formed by convergence of fascicles on the fibula. Posterior graphic of the posterolateral corner of the knee demonstrates the popliteus tendon , oblique popliteal ligament, FCL , arcuate ligament , and fabellofibular ligament .
How is the arcuate ligament replaced in the fabella?
It is a Y-shaped thickening of the posterolateral capsule, which arises from the fibular styloid and divides into two limbs: In individuals with a large fabella, the arcuate ligament may be absent replaced by a thick fabellofibular ligament.
